Abstract

The total lattice potential energy of phosphorus(V) bromide, [PBr4]Br-+(-), is reported to be 528.7+/-5 kJ mol(-1) as calculated from LATEN and the enthalpy of formation of the tetrabromophosphonium cation, Delta(f)H(0)(PBr4+,g) is 479+/-5 kJ mol(-1). The homolytic bond energy of P-Br is found to be 326+/-5 kJ mol(-1). (C) 1996 Elsevier Science Ltd.
